Caution: We Don't Know What We're Talking About

The title of this post is triggered by this bit of information:

"African Americans have replaced Asian Americans to become the ethnic group that spent the most on organic produce"

Certainly surprised the heck out of me. Source: Choices Magazine--an article by USDA/ERS--
from their summary (data is 2001-2004):

We used the Nielsen Homescan data from 2001 and 2004 to analyze consumer
purchase patterns of fresh organic produce. Our analysis shows that Asian and African Americans tend to purchase organic over conventional produce more than Whites and Hispanics. Households residing in the western region spent more on
organic produce on a per capita basis than those residing in other regions.
Contrary to popular opinion, we do not find any consistent positive association
between household income and expenditures on organic produce.
